Hey Product Hunt! 👋 I'm Twinkal, co-founder of Reloop. We built this tool after noticing that a lot of people doing cold outreach have NO idea that domain age directly impacts email deliverability. A domain less than 30 days old sending bulk email = almost guaranteed spam folder. This free checker takes 2 seconds to use. just paste any domain and you'll instantly know: • How old it is • What warmup stage it's in • Whether it's safe to send cold email from Would love to hear what domain you tested and what stage it's in 👇 Happy to answer any questions about email deliverability or cold outreach!
